Super Guarantee — Q1
28 Oct 2025
n/a
12% of OTE (FY26 rate) for staff paid in the quarter. Must clear the fund's account by the date — payment date is when the fund receives, not when you initiate.
Super Guarantee Charge (SGC) replaces the deduction. SGC is non-deductible and includes the unpaid amount, nominal interest, and an admin fee — far worse than late payment of any other tax.

STP finalisation

Single Touch Payroll year-end finalisation declaration for all employees paid during FY26. Once finalised, employees see 'Tax ready' in myGov.
Employees can't lodge their returns cleanly until STP is finalised. Penalties for late finalisation are administrative but the ATO will follow up directly.
Taxable Payments Annual Report (TPAR)

Fringe Benefits Tax return for the FBT year ending 31 March 2026 (note: FBT year is different from financial year). Required if you provided cars, entertainment, gym memberships, or other fringe benefits to staff.
FTL penalty plus GIC on unpaid FBT.

Company lodgement dates are tier-dependent. Established profitable companies may need to lodge by 15 January 2027; newer or smaller companies typically have until 28 February or later. Your agent programme tier sets the date — do not assume a single deadline applies to your company without checking.
FTL penalty starts at $313 (small entity) and scales up sharply for medium and large entities. GIC accrues on unpaid tax.
